ISL60002CIH318Z-TK

Overview

The ISL60002CIH318Z-TK is a precision low-power floating gate analog (FGA) voltage reference manufactured by Renesas Electronics. It provides a fixed output voltage of 1.8V with an initial accuracy of ±2.5mV and a temperature coefficient of 20ppm/°C. The device operates within a supply voltage range of 2.7V to 5.5V, drawing a typical ultra-low supply current of 350nA. It features source and sink currents of 7mA and is housed in a standard 3-lead SOT-23 package. The component supports an operating temperature range from -40°C to +85°C.

• Medical equipment requiring low power and high accuracy

Procurement Notes

Verify the specific suffix Z-TK corresponds to tape and reel packaging when ordering. Confirm that the manufacturer designation aligns with Renesas Electronics, as Intersil was acquired. Ensure the order quantity matches the required reel specifications if bulk procurement is intended. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Selection Notes

Select this component when a stable 1.8V reference is required alongside minimal power consumption. The ±2.5mV accuracy suits applications demanding higher precision than standard bandgap references. Consider the 7mA drive capability for driving moderate loads directly without additional buffering. Verify that the 2.7V minimum supply voltage fits within the system's available rail.

Part Context

This part belongs to the ISL60002 family of FGA voltage references, designed to eliminate the trade-off between thermal stability and power consumption. The family offers various output voltages and accuracy grades, all sharing the same compact SOT-23 footprint and low quiescent current characteristics suitable for space-constrained designs.

Replacement Considerations

Direct substitutes include other ISL60002 variants with different output voltages or accuracies, such as ISL60002BIH318Z-TK for tighter accuracy. Non-family replacements require matching the 1.8V output, 350nA current draw, and SOT-23 package constraints.
